I would like to have many things, see:
http://www.slideshare.net/thorium/the-pain-points-of-c

Also:
Let's say I want to make methods: myItem.Validate().Save().SendForwardInProcess(), I would like to have myItem subtypes to support this process: validatedMyItem and savedMyItem. But this means a lot of code! For example: I can't construct easily validatedMyItem with same property values.

So:
- "func"-keyword to be like "var" for "Func<...>"
- Pattern matching (=just easier way to type else if else if else if)
- Easier way to transform instance to sub-type

Could somebody at Microsoft write a driver for cl, so that 32 bit and 64 bit code could be compiled via a command line switch, instead of having to use vcvarsall to constantly switch back and forth between two different programs.

when clicked it would bring the current file into view in the solution explorer tree, so you don't have to hunt it down to check it in.

Merge Expression Blend and Visual Studio so I don't have to go back and forth between two different tools to program Silverlight and WPF. Its crazy to have to use two different IDEs. Blend has a terrible Xaml editor and V.S. doesn't work well with behaviors, templates, and design time data.Take the good stuff from each one and put them together. Please!

Basically give users the ability to see in a GUI the screen they are working on, so they can better design there applications GUI without having to run the build every five seconds.

Could you please include sources of Ionic.zip.utils (under ms pl) to .Net platform and speed up his implementation?

Zipping+AES Encryption is very popular. And used almost everywhere. Comparing to wrapper of 7-zip compression takes longer in 2 times and with begger size, but API of ionic is very great.

To develope web projects not only with asp

Most LoB applications have static data that seldom changes, but currently, LightSwitch still hits the database when it needs to display this data - as a source for AutoComplete Boxes, Grids, etc. Example of these entities are Departments, store locations, Territories, etc.

I propose to add a check box to the Entity designer to allow that EntitySet to be cached from the first time it is used, or even asynchronously as the application starts up.

Publish a .NET Kodu API for 3rd party extensions written in C#/VB:
- figures
- physics engine
- algorithms of all kind.

This should enable us to develop all kinds of 3D figures as well as strategy games.

Kodu is an excellent environment to teach the ideas of programming. However the smooth path to VS/.NET coding which would be attractive to students is missing.

Please enhance Visual Studio Unit Tests for better support of data driven unit test, like NUnit TestCase attribute.

[TestCase(1, 1, 2)]
[TestCase(1, 2, 3)]
[TestCase(1, 4, 5)]
public void test_Add(int x, int y, int result)
{
Assert.AreEqual(MyUtils.Add(x, y), result);
}

Such an attribute is urgently needed for testing methods with several test cases.

First step, to move sources from a team project on a private TFS server to a team project in TFSPreview/Azure
Second, to migrate the structure of the team project and data depending on the amount to transfer

The property pages Command Argument entry must be changed frequently during program debug and testing. Having a drop down history list of previous commands would make switching between frequently used command arguments much quicker and less error prone.

Today it is a lot of manually coding to build a application with a many-to-many relation.
It would be nice to have more out of the box support for this.

Often I'm finding screens may have similar custom layouts, but I need to build each one from scratch. I have to flip back and forth between screens (see my other sugg. "Allow developer to have multiple screen designers open simultaneously."), and manually tweak the hierarchy to get screens to be consistent with each other. I'd like to be able to select a node in one design screen, copy it, and paste it into another.

In the watch, data tips, etc windows, show integers with the digits grouped, by 3 if decimal representation, 4 if hex.
For example, instead of "1234567890", display as "1 234 567 890". Instead of "0x0000123456789abc", display as "0x1234 5678 9abc" (note, leading 0s should be removed).

These could be user-settable options.
